Knime Server won't start NameNotFoundException / No Service registered for ServerConfig

Hi all,

First of all, I hope that you and your families are doing alright.

Now, I am having Knime Server and Knime Executor on the same machine (Windows), both the newest versions from the download site. I had installed them a couple of weeks ago, but after a restart, the server does not want to boot up. Tomcat is still firing up and I can access it via http://server-ip:8080.

It could be that there is something misconfigured, since a buddy of mine enabled SSL on the server. Sadly, he is not able to fix it either. Thus, help :smiley:

The error from the log:

18-May-2021 16:01:58.128 SEVERE [main] org.apache.catalina.core.StandardContext.listenerStart Exception sending context initialized event to listener instance of class [com.knime.enterprise.server.pmml.models.PMMLScoringListener]

com.knime.enterprise.server.application.ApplicationContext$NoSuchServiceException: No service registered for com.knime.enterprise.server.config.ServerConfig








Caused by: javax.naming.NameNotFoundException: Name [com.knime.enterprise.server.config.ServerConfig] is not bound in this Context. Unable to find [com.knime.enterprise.server.config.ServerConfig].

I saw similar errors in the forum, but there wasn’t a solution to it - Unable to start Knime server - KNIME Server - KNIME Community Forum

Will be much thankful for a tip on where to search or even better, what to fix. Thanks in advance!


Hi @nooby ,

Can you provide us with a few things for us to investigate further:

  1. KNIME server logs located under /logs
  2. knime-server.config file located in the / folder
  3. server.xml file located in the /conf/ folder
  4. The changes made to enable SSL and the settings before they were made if possible

Please email this to so that we can have the ticket in our ticketing system and we can communicate there and set up a call if necessary. We shouldn’t post these things in the public forum.

Hi @ztrubow ,

Thank you for your reply and suggestion. However, I am not a fan of sharing the mentioned files. Thus, I still tried to find the error and fix it by myself. The simple “turn it off and on again” didn’t help.

→ Made backups of the workflows and SSL configuration, then purged the whole Knime installation (Server and Executor) and reinstalled them from scratch.

It seems like there was a misconfiguration somewhere.

Cheers to all, who tried to help. You can mark the thread as solved.
